These have been about for a while now as I developed them for my S4K (now the RS4K) track car.

These are waterjet cut steering arms that are used to replace the factory steering arms on audi strut tubes when doing a coilover conversion (or not)

A pair are used on each strut and are spaced approx 2" apart. these are welded to the strut tube and allow you to adjust bump steer (by moving the tie rod end up and down between the two plates using spacers, note that this requires a change from the standard tie rod end to a spherical joint type of rod end). You can also adjust Ackerman using the 6 holes to mount the rod end, the outermost hole is stock location (assuming the plates are welded to the strut tube with that hole in the same position as the stock tie rod end), the other holes then affect Ackerman and steering ratio, the further in you go the quicker the ratio.

4 are required per conversion.

These are made from 1/4" steel plate and can be gusseted but gussets are not required.

Install pics: (note these pictures are of the previous first generation product, the new version is much improved over the original design.

Several sets are out there already on projects that should see track action in the spring and I will get some updated pics and user feedback when available.

I've been contemplating building coil overs for a few weeks...if I'm already going to be grinding the steering arms off my housings these seem like a no brainer. With spacing of about 2" how does the height of the top arm compare with the stock steering arm? I could go measure but it's dark and I'm feeling lazy. Nice work.

Is there any way to use these without using heim jointed tie rods? I guess if not using the heim rods it might defeat the purpose. these have interested me for a while but I seem to use my car in the weather more than I do the dry.

It is really a personal preference when putting them on, I set mine to be approx 1/2" lower for the top plate.

Sorry, these are designed specifically for spherical joints. we typically use spherical joints on the inner and outer, and we use swedged rods for the arms, available from http://www.rodendsupply.com

We also use spherical joint lip seals on our installs, these are available from many vendors including Summit.

One other thing to note is the use of 'high misalignment spacers that sleeve down a big rodend to a 1/2 shaft size. The spacers to adjust bump are then simple cut pieces of tube.
